4'Claims (Cl. 126319) This invention relates -to-:a closure adapted to be detachaloly mounted inside ofxa'fiue or chimney for-closing. a lateraho pensingthereto, such as a stovepipe' opening: which opens at one I end into the flue'or chimney and at itsopposite endtothe interior of an enclosure.

It is! the primary obgiectro-fi the present invention to provide-1a fluea-st'opi or closure'dorr closing a Stovepipe opening: or tlrerlike atthevichimney or flue endxthereofrsol as: :toaprevent soot, rainwater orthe like from" accumulating. 'inthe opening and seeping past the. closure disposed: at the outer end ofthexopeninggnto xthus eliminate the staining of walls resultingsfrom moisture and soot escap= ing'irom a :stovepipe opening into a' roonror' other enclosure:

Still a further aim: oi. the: invention is to'pro vide a flue stop or closure of-extremelwsimple constructiorrcapable of being applied to the inner end of a stove'pipa' opening by: being. inserted therethrou-gh'fromithe opposite endofi said opening and which, when applied; .wil'l: cfiectively' seal the chimney or flue-rend oi: the opening;

Various "other objects and advantagesri-of the invention will hereinafter becomermore' fully apparent from: the following description of the drawing; illustrating? a: 1 preferred embodiment thereof, and wherein:

Figure 1 is an? end 'viewiinvelevationi looking toward an" end" of a stovepipeor similar opening of a chimney orfiueandshowing-the closuredi'sposed therein: and" in '1 the: position that zit will assume in passing :itlii'oughrthe "opening: in the course" of beingv tap-plied to or removed from the inner end thereofi" Figure'Z is:a:viewtakemsubstantiallyat aright angle to :Figurei l. and-rshowing the flue. stop or closure in: an appliedposition Figure 3 is a. plan viewtlooking toward the outer side of the stop or closure;

Figure-'4v islatsimilarzview looking toward the inner side thereof; and

Figure 5 is au-enlarged cross sectional view taken substantiallyv alonga plane as indicated by line 5-5 of Figure 4.

Referring to the drawing, for the purpose of illustrating." the flue "stop or closure," designated generally 6 and comprising the invention, a portion-oi one wall 1 of a chimneyis illustrated in Figures '1 and? and is shown provided with a lined bore or opening 8 having an inner end which opens: into a chimney or'fiue 9.? The opposite end of the boreoropening 8 opens onlthe' outer side of thewal'l '1' into anenclosurasuchj as a room of" 'a "house.

The stop or. closure 6 includes a. hollow shell,- designated generally I 0: having a substantially fiat inner side ll and a convex outer side l2 the edge of which-merges with the edge of. the side it and which may be formed integral therewith; The shell Ill is substantially circular, as clearly illustrated in Figures 3 and 4 anddivided diametrically into an upper section l3 anda lower section M.- The edge portions. of the sections of the. inner wall: ll aredisposedin. abutting relationship. as seen iirFigure 5; when shell ill is extended, and the adjacent edges of. the outer convex wall 12 are disposed in slightly overlapping relationship and with thelower section of the wall 12 inset. slightly as seenat. IE to receive a portion ofthe upper section. of the convex wall I2 which is disposed in overlapping relationship thereto and on the outer siddthreof, as illustrated in Figure 5.

A- relatively wide band or. ring l6, formed of sections I! and i8; is secured to and projects perpendicularly iromtheouter sideof the inner wall H. The sections. H and i8 are secured in any suitable manner as by We1ding, as seen at H) to the shell section. 13 and M, respectively. As best. seen in Figure 4, the ends of the band section l8 are offset inwardly slightly to receive the ends of the bandsectio 11 which are disposed thereover, as seen .at.2.ll and so that the exterior of-thebandor ring [6 will be substantially smooth and circular. Alrod 2 I extendsthrough the overlapping end portions. of the band sections ll and i8 and is preferably fixed in any suitable manner toand countersunk in the ends of the band sectionl'l and rotatably. engaged-with. the ends of the section [8, so that the closure vl5. can be folded on the rodZl as a pivot from its extended position of-Figures 2 to 5 to its folded-positionof Figure 1. It will also be readilyapparent that. the rod 2| will extend diametrically of the. ring l6 and substantially in alignment with the juncture of the shell sections l3 and Ma Assuming that it is desired ate-apply the closure B te the opening 8 for closing'saidopening at the inner or flue end thereof, the shell and band sections are folded on. the rod 2 I: as a. pivot and substantially to the position-as seenin Figure 1, so that the folded closure 6 can be inserted in the opening Bandwith-the rod 2| disposed longitudinally of said opening. .With the closure 6 thusdisposed, theoperator grasps the rod2l and passes the closure inwardly through the opening 8- and into the fiuet. With the closure 5 disposedwithin the flue 9, the closure can be turned toposition the rod at a right-angle; to the axis to the opening 8 after which the rod is moved toward the opening 8 so as to engage an edge of either the shell sections l3 or M with the inner side of the flue Wall to cause the closure sections to be rocked toward extended position, as illustrated in Figures 2 to 5. When the closure sections have been extended sufficiently so that the shell 12 cannot be drawn back into the wall or opening 8, the ring or band 15 is moved into the opening 8 by a pull exerted on the rod 2| and in being so moved, the edge portions of the shell sections l3 and M, which are disposed remote from the rod 2| will engage the wall of the flue 9 for rocking the closure or stop 6 to its position of Figure 2 with the band 16 engaging the inner end of the opening 8 and with the marginal portion of the wall I l bearing against the inner side of the flue 9 around said opening. The lower edge of the convex outer side of the upper shell section I3 will overlie the adjacent portion of the lower shell section so that soot, moisture or the like will flow over. the convex shell wall l2 to fall or drip therefrom below the opening 8 so as to prevent soot or moisture from collecting in the opening or bore 8 and seeping into an enclosure located at the right hand end of the bore 8, as seen in Figure 2.

Various modifications and changes are contemplated and may obviously be resorted to,

without departing from the spirit and scope of the invention as hereinafter defined by the appended claims.
